You can never make a full decision on only a little information. But most times, all the information's not all readily right there for you to see. This is where your intuition helps a lot. If you're feeling a lot of hesitation but logically it sounds fine, then it may not be something to dive into. If you're feeling drawn to it, then either it's the right thing or there's a lesson in it that a part of you wants to learn. In uncertainty, stay very aware of your feelings throughout the day. If the feelings are more heavy than expansive, it may be something you let go without having to find out what those feelings were indicating early on. If you have a lot of really good feelings inside even though doubts may enter your mind later, then going with it is probably a much better road to follow.
Let your intuition be your guide, but keep your mind alert to process what that sense is telling you.
