Do you know that the closest star to earth is 4.3 light years away and the farthest start is about 13 billion light years away?
One light year is the distance on object travelling at the speed of light (2.998×10^8 m/s) will covers in one year, meanwhile the latest get ever built on earth moves at a speed of 2000m/s a very small fragment of the speed of light.
The star you see up in your sky today was there about 4.3years ago it might even not be there now, the start you saw falling yesterday probably fell even before our fathers were born.
Can you see how insignificant we are amongst the creations of the mighty Creator? And yet we see ourselves as a big deal, we see ourselves as self sufficient.
We look down on those that we are slightly favoured over with contempt, we take people for granted, we treat others with so much hate that we raise ourselves night above them.
You are nothing, you never were and never will be in the glory of the Almighty. Everyone has a right over everyone, we are all humans and we all from the same creator. He favoured you over others so you can show love to others, so that help others, so that you can be a shoulder to cry on, so that others can lean on you and yet you live as if it your might. You forget that the life you're living recklessly is not yours, the life you have is borrowed because no one promised you tomorrow.
I invite you to show love to other, share love for this is the only and sure way to better our society for indeed "None of you is a better person until he love for his brother what he love for himself"
Be humble!

Knowing that God is the ultimate being and that prayer can't be waved for anyone aspiring to be successful in his endeavours.
The #1 SUCCESS SECRET is not
SETTING GOALS or
HARD WORK or
PLANNING or
STARTING EARLY.
The #1 success secret is KNOWING HOW TO ASK FOR HELP.
Knowing that we need help and asking for help is not a sign of mediocrity rather it is a sign that we are sensible and courageous.
Rather than labouring for weeks and getting nowhere, we should set aside our ego and ask for a hand and in the blink of an eye we are soaring with the eagles. We all need help at one thing or the other - at one point in our lives.
Its amazing how many people are willing and to what length they can go to help us if only we asked.
We should always keep it at the fore front of our memory that help won't come unless we seek it.
