Goals can be sound or questionable based on the nature of your desire, for your goals control your actions. While it’s great to achieve worthwhile goals, some are not worth pursuing if you set out to accomplish them questionably.
For example, if one of your goals is to accumulate significant wealth, you have to determine how you plan to achieve said goal. You can opt to build wealth through traditional avenues such as gainful employment and sound investments, or you can pursue non-traditional methods such as playing the lottery, marrying into money, or robbing someone of it. The means you use to accomplish your goal is just as critical as the goal you are trying to accomplish.
