Unless you have a lot of capital, it's not about preference, it's about reality. The more you work on, the more you spread yourself thin. The more you work on, the less likely anything is going to succeed. If you want something to really take off, you need to pick one. There should be one idea that really jumps out at you above the rest. If not then maybe you haven't found anything big enough yet. In that case it may be helpful to simultaneously explore multiple ideas. But pick only one eventually.
