Life does not become easier and life is always challenging and an uphill. But when you focus on what you can control and constantly push yourself to be the best version that you could be, constantly put yourself into challenging situations and put yourself through voluntary struggle and pain everyday by exercising, eating healthy, sleeping on time, planning time for family and taking care of yourself then you become stronger and capable to deal with the inevitable challenges and uncertainties in life. In this process life did not become easier by you acquired the skillset and adopted to deal with life more efficiently.
