How to not get bored in Scrap Mechanic

Go on raids to get parts in survival, and chop down trees for wood. Then build something with those resources that can destroy a Farmbot. Then find a Farmbot and ram your creation into it until it explodes. Then use the master key to open the elevator. Once you get out of the elevator, (hopefully you have a spud gun) go fight the tape bots and get stuff from them and the warehouse. go back down the elevator and repeat the process over and over starting from finding a Farmbot.

Build a challenge and save it, then play it by yourself or with friends or upload a challenge from the Scrap Mechanic workshop. Then play the challenge you uploaded from the workshop. If you don't want to do either of those, get better at scrap mechanic by playing the Master Mechanic Trials.

I have a challenge that I have not gotten bored of yet, called Castle Defend.

Build a creation from a movie or show you watch, or just build something that we have today. You can also upload creations from the workshop and test them out, or do challenges or battles with them. You can also build tiles and worlds for Creative. (If you want friends to be able to join a custom world, then you have to publish it.)
