Some1 once told me
“When you decide to help somebody, enjoy doing it and do it to the best of ur ability.
Once its done walk away, and be happy that u have played your part.
When you get a thank you, smile and be happy.
When the person you helped is not pleased, then smile knowing that you did what you had to do with no regrets on ur part.”
The advice is so simple, so easy to say, so painful to live with, but it keeps a smile on my face everyday.
