Ego or not
If one has to choose a direction or activity how does one know if it is from ego or just natural? It can be hard to know the difference. One way of approaching such a dilemma is this; just make the activity another choice, something that is before you, but don't be for or against it. Be willing to let it go if it reveals itself as an ego choice, or continue it if it seems honest. It can even start out from ego but turn into something reasonably healthy.
In doing so the decision is not life and death. You are bigger than the choice. Just have a sense of peace about you and pursue it. If you fear a vacuum if you reject it, don't. Life will provide and fill in the gaps and still pass through you in a meaningful way.
