This is a high risk for an inferior Te grip in an INFP though, which can lead to Ne eventually, but can also be the long, frustrating route. I think interacting with people or doing things which allow for more conceptual trains of thought to form is a better way. Task work is likely to bring out SiTe in an INFP, and at best, just prove a distraction while they get some chores done (but hey, that IS useful in other ways).
Anyhow, I find interacting with others useful, especially if I hold off on any judgment & reflection while doing it. It allows my perspective to readjust a bit. This will backfire if you start comparing yourself to people, or making other conclusions which amounts to Fi butting in again. You also have to be careful not to overextend yourself energy-wise.
I also agree with [MENTION=4894]animenagai[/MENTION] that you're probably limiting yourself. For INFPs, I see this as creating imaginary obstacles, because you've self-imposed some Fi standard on yourself that is not really as necessary as you're making it to be. Ne tends to work well with innovating itself out of boxes & obstacles, but that's only if Fi ideals allow it to move freely. Try & broaden your idea of what is necessary for you to be happy or to move forward, even what "moving forward" means.
