This is what everybody establishes in their mind, “Someone like a little elderly woman can no longer make an impact on the world.” This is not true in God’s eyes. If she is a dedicated praying Saint, God knows her heart and remembers well and ponders her requests to give reply.
Mother Teresa was like that. Please enjoy reading this story:
“When once a chairman of a multinational company came to see me, to offer me a property in Bombay, he first asked: ‘Mother, how do you manage your budget?” I asked him who had sent him here. He replied: ‘I felt an urge inside me.’ I said: other people like you come to see me and say the same. It was clear God sent you, Mr. A, as He sends Mr. X, Mrs. Y, Miss Z, and they provide the material means we need for our work. The grace of God is what moved you. You are my budget. God sees to our needs, as Jesus promised. I accepted the property he gave and named it Asha Dan (Gift of Hope).
You probably need this. Here’s some more advice:

Humble Obedience
Make us worthy, Lord, to serve those people throughout the world who live and die in poverty and hunger. Give them through our hands, this day, their daily bread, and by our understanding love, give them peace and joy.
I heard the call to give up all and follow Christ into the slums to serve Him among the poorest of the poor. It was an order.
I was to leave the convent and help the poor while living among them.
Helping the poor
When a poor person dies of hunger, it has not happened because God did not take care of him or her.
It has happened because neither you nor I wanted to give that person what he or she needed.
Don’t Be Mean to Jesus
You and I, we are the Church, no? We have to share with our people. Suffering today is because people are hoarding, not giving, not sharing.
Jesus made it very clear. Whatever you do to the least of my brethren, you do it to me.
Give a glass of water, you give it to me. Receive a little
child, you receive me.
Time with family
Everybody today seems to be in such a terrible rush, anxious for greater developments and greater riches and so on, so that children have very little time for their parents. Parents have very little time for each other, and in the home begins the disruption of peace of the world.
Path to peace
A sacrifice to be real
must cost, must hurt, must empty ourselves.
The fruit of silence is prayer,
the fruit of prayer is faith,
the fruit of faith is love,
the fruit of love is service,
the fruit of service is peace.

Materialism
The more you have, the more you are occupied, the less you give. But the less you have the more free you are. Poverty for us is a freedom. It is not mortification, a penance.
It is joyful freedom. There is no television here, no this, no that. But we are perfectly happy.
The Law of Kindness
Speak tenderly to them.
Let there be kindness in your face,
in your eyes,
in your smile,
in the warmth of your greeting.
Always have a cheerful smile.
Don’t only give your care,
but give your heart as well.
God’s Love Over our Frailties
Give yourself fully to God.
He will use you to accomplish great things on the condition that you believe much more in His love than in your own weakness.
Silence
Before you speak, it is necessary for you to listen,
for God speaks in the silence of the heart.
Poor In Love
There is a terrible hunger for love.
We all experience that in our lives – the pain, the loneliness.
We must have the courage to recognize it.
The poor you may have right in your own family.
Find them.
Love them.
A Clean Heart Is GoodA clean heart is a free heart.
A free heart can love Christ with an undivided love in chastity,
convinced that nothing and nobody will separate it from his love.
Purity, chastity, and virginity created a special beauty in Mary that attracted God’s attention. He showed his great love for the world by giving Jesus to her.
