have u ever made any decision and to only regret it later ?

i find it very frustrating whenever i think about it. just wish i never did it.
sometimes people say, follow your heart. listen to what your heart tells u to do. that is the best way to finalise ur decisions whenever ur undecided or confused. but is it really so easy ?

it's disheartening when u realised u hav made the wrong move.
and what makes things worse is that u can never turn back time to mend it.
