That depends on a couple of things. If your competitiors continue to work on theirs, they may overtake you. The quality of your backlinks can also play a part. Just keep an eye on it and if it drops then do some more backlinking. But generally you can move on to the next keyword. It is advisible to still do some backlinking to the original keyword every now and then though, just to be consistent.
If you're targeting several keywords, then it is much better to do divide your time and link building effort accordingly. Sudden stop of link building process may cause some changes in SERPs ranking, and it is advisable to do the process in a constant (but not too aggressive) manner.
