Your world is defined by you. You chose the boundaries that contain you. For example, the local area you live in, the extent to which you know it is based on your choices. There will be paths you’ve never trod, roads you’ve yet to walk down. The reasons for not going somewhere may be perfectly valid, and there are areas you could possibly never go, like the centre of the earth. But your boundaries are not just physical, this covers all areas of life.
The question of most importance then is how do you chose your boundaries. How can you be expected to decide whether you want to venture into the unknown, as, by definition, there is no information to base your judgment on? The counterpart of this of course that if exploring everything is impossible, then boundaries will need to exist, so how do you decide what those are? Will it just be those things you don’t have time to explore, or will there be things you decide should be avoided and if so, how can you test whether the unknown routes contradict your conditions?
There are essentially 3 potential solutions I can think of, and only three. The first is that you just have to decide yourself based on what little you know. Your decision may not be fully informed, but not only will you have full control, but it’ll be quick and easy to reach a choice. The second is the one that I imagine most people use, that of deciding on their own for most of the time, and when the choice is particularly complex, they seek the advice of someone else, and let them make the choice for them. This is a compromise that leaves people pretty happy, as they are still in control for the most part. Even when they hear the advice they asked, they can then chose whether to accept it or not. There is little difference between this and option one, except that many following this can believe the lie that they have no control. They can trick themselves into thinking that they leave all the big decisions to others, or more often one specific other individual, and just do all the little ones themselves.
The third option is the hardest. It is that of letting someone else make all the decisions for you. You have to truly trust that they will be there always, else it just won’t work. Sometimes, this can look like the other two, as the leader’s decision may be for you to decide yourself. Those who live by this option are dedicating their life to following something and fight daily against their natural instinct to be quick and take the easy option. They obviously have a reason to trust their guide with their whole life and to follow them unswervingly. They may not be entirely successful, but the objective remains unchanged.
Of course, we make the choice of which of these options to take daily, and any option we chose is not permanent. In fact it is a constant action of choosing which of these routes to take, and we must be sure that we are happy with the choice we make, as one thing that is for certain, we cannot go back. As soon as we have crossed a boundary, although we can step back behind it, we have nonetheless made the crossing. So choose wisely; its you who’ll have to live with it.
