Business
You need to do the reps and put in the hours... To me starting a business is exactly like going to the gym, you feel energetic and excited at first and then it starts to get boring and a little bit stagnant. This is exactly the same for business, it feels good to begin with and you're really excited but then life comes along and that initial energy has dwindled away. Ultimately if you want to see any results you need to put in the work and persevere.
