If we only focus on our destination the end will always seems a long way off. Stepping stones are what gets us to where we are going. Rewards are good for the soul. Breaking things down into manageable targets and rewarding yourself for achieving them keeps you on track.
If your only focus is the destination ( whatever that is) will make you feel like you will never achieve it.
Small achievable targets will keep you on track. People rarely FAIL they simply stop trying. Learning is a step by step process. We often get distracted and don’t take the next step, we need to keep moving forward to achieve your goals.
