To really leave a legacy and progress a person must come out of their comfort zone. Meaning if you dedicate a little bit of time to religion and seeking knowledge you’ll get nothing back.
If you devote everything you have you’ll get something back.
Some of the people of the past would urinate blood when seeking ilm as they would travel long distances in hot weather and have no water to drink.
Meaning you have to break you back if you actually want to get far.
