Never give up
Source
what do people usually face in life most?
Why do people easily get discourage over something in life and even get depressed over somethings? Life is not always what we think it would be, infact there's more to life than you think, the fact that this thing is going so well for Mr A and not well for Mr B, does not mean that is the end, my dear life goes on. Be always be ready to start up again when ever you fall, after all even our Lord Jesus Christ, on his way to be crucified he fall down three times and he got up again, so in every tribulations in anything at all you faced in life while trying to succeed and if by any chance you end up failing instead at some point, please do not give up.
2 Chronicles 15:7
But as for you, be strong and do not give up, for your work will be rewarded.”
Galatians 6:9
And let us not be weary in well doing: for in due season we shall reap, if we faint not.
know your full potential
Do you full know your potential? to no frank, one fully know is true potential if he remain doubting his/herself, start trusting yourself and start believing in yourself because you don't expect someone else to do that for you, do you?
Try not to give up too easily
When you feel like giving up, you are missing out on what God has to offer.
Philippians 4:13
I can do all things through Christ which strengtheneth me.
