Focus is important in pursuing anything in life. It is possible to pursue more than 1 attempt, depending on how much energy and effort you would require to accomplish them. It is also very important to have support in what you pursue. If you happen to have a team to support you, to accomplish different responsibilities and work to reach the goals, it is highly possible to pursue more than 1 idea simultaneously.

Neverdelous, focusing on one thing at a time is never a waste of time. It gives you more awareness to all your attempts, hence you are more likely to see your direction more clearly.
