I've started to fall away from cubing. I want to get back into it, but I have no idea as to how. I need ideas for something to spark it all back up again.
Try to figure out *why* you want to get back into it - what is driving you deep down to feel this way: is it the solving, designing, collecting, or simply being part of a community of like-minded people? Then once you've pin-pointed which of these elements you like(d) most about cubing, ask yourself how and whether you could satisfy these needs in other ways, and try those activities in parallel with cubing, see what you gravitate towards.
Also, think about taking on a specific cubing "project" or challenge and set yourself a goal that will keep you engaged (like designing and making a puzzle, solving an entire series of puzzles, entering competitions, creating a local cubing club or website, etc.).
Good luck and hope to see you drop by at least occasionally.
