What are the most powerful habits?

Being brave. The willingness to do uncomfortable things for future good is priceless.
Uplifting self-talk. Your thoughts should build you up instead of tearing you down.
Questioning things. You aren’t a sheep. Don’t do something just because everybody is doing it.
Encouraging others. There is enough negativity in the world, why create more?
Integrity. Never pretend to be someone for social approval.
Build strengths. Develop a skill you are naturally good at.
Being curious. You should be on the look-out for learning new things because you can never know enough.
Being proactive. Problems are inevitable, focus on the solutions.
Saying No. If it’s heavy let it go. Find a way to do what you want.
