These days people look at their personal phone wallpapers an almighty lot. So, set your number one goal as your mobile phone wallpaper, as a constant reminder that's what you're aiming for, and not to veer off course.
Below is my number one goal. It's simple, all I want is to move to a nice house with a garage (ideally a large/double garage). No more wasting money on other things I don't need. I don't desire anything ("desire is the root cause of all suffering" and all that), all I truly need is air, water, food, health, safety and security.
