1997 Chevy S-10 My truck wont start.

Hi and thanks in advance for you advice! I drove to wal-mart the other day, when I came back out to start my truck it wouldn't start. Everytime I tried to start it, I would hear one single click each time. I sat their awhile and I tried again, eventually my truck started. I drove it to my next destination and when I returned to start it. It wouldnt start, I couldnt get it to start this time. Same click sound. My lights work, the radio, the air, and all that. I checked the battery cables, one was lose so I tighted it and even had it jumped. My truck still wont start. About 4 months ago my starter got stuck, as in when I started my truck and turned it off the starter was running erracticly and got so ho it burned up. So I got it fixed, and then about a month ago it did it again but this time the starter stopped running on its own before burning up so I didnt get it replaced but it was found my truck had a corrided ground cable connected to my battery, so it was cleaned and it ran fine for awhile, and now this is happening. Help please!
