Today's sacrifice is the benefit of tomorrow
What we call today as a sacrifice or things that we stop doing will always be the benefit of tomorrow. As long as everything we give up with the goal, either to do something productive or very helpful for the future.
As human beings, it is normal for us to feel bad for things or great enjoyments that we leave aside to dedicate ourselves something that satisfies us, and benefits us, as is personal development, such as knowledge.
For many of those things, today will affect us a bit but believe me later we will achieve our goals and objectives that we sometimes visualize.!!
