Set a specific time that you go everyday, and treat yourself afterwards to help reinforce the habit.

Make it as easy as possible to go, and as hard as possible not to go. Head directly to the gym to or from work. Pack your gym clothes in advance. Create a gym routine that takes less time or switch to a closer gym/home workouts. If you regularly skip for the same reason (say, feeling too tired), remove that obstacle (have caffeine, go to bed earlier, go to the gym anyway and suffer so you are motivated to sleep enough). If you don't like working out now, change your program so it's more fun,

For context I’m a skinny tall guy and going to the gym feels weird but I want to get a little bigger

There’s really no secret to it. Aside from having an enjoyable workout routine and adequate diet and rest, you have to find it within yourself to do what must be done, regardless of how you feel. Enjoy motivation when it comes, but do not rely on it. This is the difference between those who succeed and those who fail. Do this, and your goals will be inevitable. Nobody and nothing will be able to stop you, it will only be a matter of time.
