The journey that you are currently on will soon be over and a new one will begin.
Happiness isn't about working yourself into an early grave so that you can buy things that you don't need in order to impress people that you don't know or like. Don't get caught up going round and round in a cycle of endless consumption. It won't bring you the happiness that you seek. It's just a distraction.
A weakened passion can be revitalised. Feed your passion and watch it grow and strengthen.
