How to improve concentration time?

Question

In a day to day life .I have realised that my concentration or focus time decrease . what should I do for better results.

Answer 1

It would be nice to have a goal, or something to motivate you, but don't overwork yourself if you think you're reaching your limit, or having a headache because of something that you don't understand, always remember to take a break, and come back to it later

Answer 2

my answer is the same as Nick,
take a break, and come back later.

@Martin Taylor doesn't that used for working at late-night purposes XD

not relevant to the question:
"I'm very glad to him"
hmm, that line sounds like you're gonna suggest our answer to your friend, which is uhh weird as you're asking for help in the rest the description.
