Great quote from an old man met at a wedding:
"In the 1st third of your life you worry lots about what others think of you. In the 2nd third of your life you say 'I don't care what other people think of me'... which is you still thinking about what others think of you. In the last third of your life you realise.... No one was ever thinking about you... They were all too worried about what people were thinking of themselves."
Focus on you for your reasons. Don't get distracted by others. Sharing what you do on social media isn't going to help you as much as getting up and doing more.
