It is not unusual to find yourself exploring different approaches when you combine enthusiasm with the vast amount of information available. The best approach is to simply be consistent, so pick one and stick to it. Faith and confidence are essential to being consistent, but difficult when you are drowning in information and ideas of "techniques." That being said I enjoy reading about different approaches to meditation, but rarely change or even cycle my approach. If you want to explore/experiment then occasionally add an extra session to your day to do so, but keep with your main approach.
In a more general sense it may be beneficial to either associate yourself with a tradition (go on retreat for example), join a meditation group, or seek out a teacher. If you are isolated (or in the meantime) pick the approach that you have some sort of inclination for, or if you can be objective, consider the one you should
be doing instead of the one you are inclined towards. For example an analytical mind might be inclined towards insight, but could benefit greatly from serenity/concentration or metta for "balance." I occasionally shift approaches if there is a very
good reason to do so. For instance I generally practice samatha with breath as object and the rim of nostrils as point, but if I find myself to be unusually angry or depressed I practice metta first, or if I am being assaulted by ants or mosquitoes then I practice elements (in regards to the body) or corpse contemplation, then get on with my regular practice.
Don't worry if your meditation "goes well" or not. Often it is the difficult times that seem to be most beneficial in the long term. Anyway it is what it is, so just stick to your practice and let whatever happens happen. Just do your best concentrating, contemplating, noting or whatever it is you decide to do. You've got 7 months under your belt
so don't burn yourself out or let yourself get discouraged!
