it depends on you desires. But acquiring it many times reguires a struggle so that you can take from the bad and build to the good. All things that are considered worth pursuing require struggle examples a in shape body, a clean organized house, building an online business. They all can make us happy but require a struggle or work to acquire.
I don't think I've learned much about achieving happiness really. For me acquiring it means being in peace with yourself and with your loved ones and being excited about something. Mainly those are internal factors.
