If you dont give them to yourself, then you wont find them elsewhere. And, you can give them to yourself at anytime. “Good job watching that tv show”, “Good job saying hello to the neigher”, " pretty nice how you can walk to and fro" or"think thoughts", “most species cant do that”. Give them to yourself all the time, nobody else will. Dont hold your self to only appreciate yourself if you were to do certain things or unobtainable things. If you dont give yourself positive thoughts, theres a good chance all youre giving yourself is negative ones.
