Post in a newspaper for piano partner and do some duets with them. It is always good to work with someone, you both will motivate one another. There are also music groups at universities/college which meet weekly, people get together to share their music on all instruments.
Do small private concerts, or public ones, whatever you think you can manage, if you only play for yourself you need to have self motivation. Not all of us are like that, a lot of us get our motivation to work through other people, which is not bad at all, we are here in this world for one another afterall.
Also its important to always keep listening to music, because that itself keeps you musically healthy. Make lists of pieces you would like to learn, get the sheet music for all of these pieces even if you aren't going to learn them or they are beyond your ability. You can always section out the music and make it more presentable(color, commentary, highlight groups etc), anyone can do that you need no physical ability to play piano for that. One this is done you are already closer to learning your music. Rather than starting at black and white notes, this preparation increases efficiency in learning your music, and hopefully creates some inspiration to start learning them in some way.
But I really can't stress how important it is sometimes to have music buddy(-y +ies) lol, someone who you can share your musical journey with and whom you can learn from and teach.
