What i want

Sometimes, i do wondering..will i really get what i want if i want, yea... Maybe i will get it in future, but what i want is get it now, not in future......if like that , will i get what i want now but not get what i want in the past??then what i want now will be what i want in future or not? Then what for i want it in future if i want other thing in future....will it be what i want...i just want...not to be want....if cannot want, just wait until i don't want as what i do to what i want....:/
