Make short term decisions based on curiosity and newness. You can't do the same thing a get a different result. So if you're trying to get a different result, choose the path you haven't taken yet.
Long-term decisions can be made by focusing on the intention and letting go of attachment to the result. For example, say you want to find the love of your life. You don't make decisions about dating someone based perceived qualifications as long-term lifemate material. You detach from the result, i.e. this guy may or may not be lifemate material but that's not the reason I'm going to go out with him. For some things, you have to take the next step in order to get enough information to take the step after that or quit.
So instead, you date with the intention of finding a the right person, but not caring if this particular date is the right one or not. You date because he/she is cute and you want to get to know them better. Then you get enough information to decide whether to go on a 2nd date which will give you enough information to decide if you want to go on the 3rd.
You make the decision that leads to enough information to make the next decision.
