How to be strong?

[st.martin.02]

Go n learn mauy thai than nxt the next time u not happy with somebody can make him KO!!... hmm think i've been watching too much of contender asia

I find that I am a coward

When my colleagues shout at me and blame me for things I didn't do I dare not shout back even though I am innocent

When a person next to me in coffeeshop smokes in a no-smoking area, I dare not tell him to stop

When somebody cuts me off on the PIE, I dare not horn

I keep all the hurt and I am feeling very bad about myself

How I can become strong and fight back?

Any bros can coach me how to be strong
