Researching interests but not actually taking part

Often it seems I have an interest in something and can read and read and read and research about it but when it comes to actually applying myself to take part in said interest, I find it difficult to get myself started - knowing where to start, what to do. Or I force mself to start and it feels half arsed or I don't seem to get anywhere with it. It feels like I'd rather just read about it and collect "favourites" in my bookmarks but never actually do anything with them. Can anyone relate to this at all
