Work hard now and enjoy later doesn't sound or seem bad but it is not whole truth. Sometimes, regardlessly of the task or goals, it is good to enjoy the moment: live in the moment while working for the future.
I really do not buy the idea of pursing success by cutting off people and many enjoyable things. I understand that some process of success will require to be alone and all that but it could be done less intensely. It's a good thing that you no longer think or believe such.
I think the moments are very precious and the thing we can enjoy may not be enjoyable in the future even if we achieve success. We need to regret in that case. So balancing everything is necessary and I learned it in a hard way.
