Just show me how I should search on google:-
"one who dig pit for others falls into it himself" or
"Try try again, you will gain"
Well, for a start, and I know you're not a native English speaker, but you've got to get the English right.
It's a terrible thing for non-native English speakers that the vast majority of Internet posters
are English speakers, and while it is far from the case that they all use correct English spelling and grammar, you'll get much better results if you do. For example, compare these results:
one who dig pit for others falls into it himself
"one who dig pit for others falls into it himself"
he who digs a pit for others, falls into it himself
"he who digs a pit for others, falls into it himself"
See the difference? The first, without quotes, gets you many pages that contain the words dig, pit, others in totally useless context. The second, with quotes, but with b0rked-up grammar, gets no hits at all. The last two, with correct grammar, get the best results, and by doing this I was able to find out that variously attributed as a Czech, Hungarian or German proverb.
It's hard, I know, when English grammar is so unlike your native language. But I'm sure that you would have got more hits if you'd actually searched in Czech. Use the Czech words, get Czech pages. Or see Googles
language tools. You have to use the language correctly to get the best results. If in doubt, ask.
The correct English version of your second is "If at first you don't succeed, try try again".
