Making a strategy for success is key. If you want a fighting chance at success, may I suggest writing down your goals? Just the exercise of of thinking about and writing down your goals increases the likelyhood you’ll achieve the goals.
For me , I need a clear picture of what success looks like. I’m not aiming for perfection either. I try never to view any experience as a failure, but a chance for improvement. For goals to be met ,sustaining a change in behavior is critical. Make goals positive , and don’t punish yourself along the way.
