What’s a surprising long term investment to career success?
Being likeable.

It doesn’t mean you agree with everyone on everything.
It doesn’t mean you go after currying favour.

It means you:

1. Act with respect
Whether it’s a senior, junior, office peon, security guard, or your colleagues. Acting with respect irrespective of how they look, speak, dress, the college they went to or how much they earn, speaks a lot about who you are.

2. Don’t complain. Ever.
People who are constantly complaining suck the energy out of you. You wouldn’t be doing the same to others.

3. Embrace feedback.
You may or may not agree with every feedback you receive, however, if you listen to the objectivity of the message, it will only work out for you.

If people like you, life will be easier.
