I am determined and train to win.

[Sarah-Betty]

Is this sentence correct?

Every time I take part in a competition, I am determined and train to win.

Is the use of "my or me" necessary here?

My parents were proud of me for just (my/me) trying, and I was proud of myself for being persistent in pursuing my goal.

Every time I take part in a competition, I am determined to win and train for it.
My parents were proud of my mere attempt, and I was proud of my persistence in pursuit of my goal.

Thank you.
Are my own sentences wong?

In your second sentence, my/me is not necessary. The first sentence is OK, but the training does take place before the competition.

 

[Matthew Wai]

I think the speaker takes part in the competition as soon as s/he enters it. Then the training starts.

 

[Matthew Wai]

Then use 'enter' instead of 'take part in' in the OP's sentence.

I'd change the order of "win" and "train" in Matthew's suggestion. You train for it first and then, hopefully, win it.

Every time I enter a competition, I am determined to train for it and win.
