Potentially has potential

Is simply knowing that I have the potential to do something enough? Even when validation comes from others, it seems useless, unless it comes from within. Like a switch that resides somewhere deep within me, it feels inaccessible, until it eventually just clicks. It could be a conversation with someone, praise over my work or doing well on an exam. I experience validation externally, however, the click comes from within me. I can feel it driving and compelling me. This click, seems to be happening more often lately. I wake up, I force myself to go to the gym even if I have a headache or just simply don't want to. I come home, satisfied and my internal high five flips the switch and I feel ignited. I am finding that the only way to continue to discover my potential and fuel this feeling is to keep on striving towards things. Whether that would be working out on a day that all I want to do is lye in bed. Or making food on a day when I feel lazy and wanna order take out. Maybe even prove myself wrong and do well on my exam tomorrow that I have been somewhat studying for... I guess what I am saying is, the only way to know how much potential I do or do not have is to try the things I am not sure I will be good at. While not expecting to be an expert at my first try. Like I am learning with my recent attempts at yoga; I cannot expect to take my body to new physical limits and not potentially wake up sore in places I have never been sore before. Right? Potentially.
