The Best Mindset to Have!
_
1. Saying “I don’t know” is a smart strategy, rather than saying what you are not sure of.
2. Realise that your actions have consequences.
3. Isolate yourself at times from everything but never from yourself. Ignoring reality won’t make them go away.
4. Don’t read success stories, you will only get messages. Read failure stories, you will get some ideas to become successful.
5. Don’t measure life in terms of money, measure in terms of freedom.

6. Set an intention to bring positive energy to everything you do.
7. No excuses for weakness please! Your excuses will escort you to the grave.
8. To protect your sanity, become selfish with your energy. Stop giving it to arguments on the internet.
9. Remember, 99% of your biggest worries will never come to you.
