Nothing matters. Life doesn't matter. The time between this instant and your death is instant. At one point we all die and our memories are gone. The only point is to not suffer along the way as much as possible and prevent other suffering in the world, but even that is fleeting and matters only in the instant.
Therefore you need not change, especially if it takes more effort. Only change if you truly desire it, otherwise strive for contentment with what you have, look for things that will make your time existing less miserable and ensure time does not slow down and seem to become endless.
In the end none of it matters, and due to the nature of the universe, the basic rules and mathematics, even our decisions are predetermined. They are based off the experiences we have had, leading back to when we had no choices. Everything will play out the way it should mathematically if we had enough information.
So sit back, relax, don't stress, enjoy yourself as much as possible and wait for the ride to be over.
