Getting anxious is normal. Especially because of external factors.
You can control things which are controllable. Worrying about results builds pressure. You do your best.
If somebody doesn’t realise your worth, try to explain them once. Not twice. Walk away. It’s their loss, not yours.
If your intentions are good, you’ll do well in long run. Vice versa.
This applies to business, dating, friendship, relationships, career & general life.
