Yeah if success was easy everyone would be successful. This alone should give us enough reason to stay resilient no matter what life throws at us. Concerning the issue of sleep that is one area we should work on. A person who sleeps all through the day or can't sacrifice this things such as that will not achieve much. The reason we hear of great men like Jeff bezos, bill gates, amancio Ortega and the rest is sleeping about three hours just a day. That's one great sacrifice we must be able to pay.
Apart from that we also have learn time management. As avoiding sleep and doing nothing is still tantamount to failure. We must be productive in anything we do. It's also important as you highlighted to look up to the God of all flesh and Father of all Spirits has we alone that can don't alone. We need his guidance in all things so we don't make bad decision. We need the need Spirit to lead us in all things while we also play our part. Yeah indeed no billionaire ever made through a job but sometimes we have to start from somewhere while aiming to becoming to becoming financially free. At the end of the day, we all need balance at the appropriate measure to achieve success.
