try my best 或者do my best就可以了，这两种说法比较地道
Be the best of youself(myself).
有一句传播力很广的广告语是这意思：To be No.1. to be 去做，去成为。 最好的，The best。 自己ownself 做最好的自己：To be the best ownself!(yourself)
As to most of us, to be the best maybe means making a lot of achievements, getting high grades at school, earning a lot of money, etc. Someone might say, ‘Yes, I just want to be the best and this is actually the life I want to ...
可以， be your personal best 没错 例句： I want to be my personal best in whatever I do.
i will be the best one my self 这个是在百度翻译，翻译出来的
做最好的自己 Be the best version of you
百度翻译：Strive to do their own google翻译：Strive to do their 在百度找滴（坦白了） 可以自己找找翻译工具，
Do the best for your own good, do not care about the others' opinions.
be the best，to meet better you
