I have a 2012 Macbook Pro that I hope lasts forever. I upgraded everything in it I could though, CPU, RAM, screen, etc. The biggest and best change I made to it was replacing the main HD with a nice SSD. Now it can run everything I need, except some games. I usually had 2-4 VMs running something throughout the work day. I also took out the optical drive and replaced it with a OWC adapter and another SSD. The last thing I do is back up everything I need, wipe and reinstall everything. I usually do this once a year or when needed, and it helps quite a bit with it feeling / acting slow. (not sure if you can easily upgrade the hard drive or not though, but it made a world of difference for me)
