I personally believe that sometimes we are so used to do some things, and we feel so good at doing them -because we have been doing the same for a lot of time and, because of this, we do it well- that we miss a lot of another things that we don´t do in order to keep everything as we have it and don´t mess up everything. But sometimes that could be quite tirying, so as boring.
My idea right now is to cross that line, to leave the "often" things and/or activities to find out new things and/or activities we thought they would´t fit with us. That´s.
