Practicing gratitude is easier said than done if we are not used to doing it. Yes, it is a habit. Doing a habit is easy because it is autopilot. And because practicing gratitude is a good habit, it is even much more difficult to start.
Let me make this a bit clearer. When we are starting to do something hard as a routine, like waking up early, doing the housework, or workout, it certainly feels heavy. On the second day, we really want to quit. However, when we are usually coming to work on time for example, and then one day we suddenly come late, we have an urge to come late again just to try. And I assure you it feels good because there is a feeling of freedom; free from a routine, free from obeying the rule. Then if we make it as a habit, we don't need a longer time to create it as a habit.
Don't you think it is weird when it feels hard to create a good habit while it feels so easy to make a bad habit? Though calling it as good or bad needs different points of view, we can still agree that gratitude is something good. And, yes, it is rather hard to practice it every day. That is because human minds are full of big, busy thoughts. Then, of course, because gratitude is something small, it is unthinkable to practice.
So, how should we practice gratitude until it becomes our habit? Should we follow some random motivators telling us some steps to practice gratitude? Yes, perhaps we can. However, we fail to proceed just because we suddenly know that those motivators are not as great as we think. We get disappointed knowing that our role models (a.k.a. those motivators) are just a normal human being. They don't do what they say. So we stop practicing.
Or should we force ourselves to make schedules to practice? For instance, we say energetically: "Thank God I'm still alive!" every time we wake up in the morning. That is a good idea to do. It can energize us to do our activities for the whole day. We undoubtedly hope that we wake up fresh every morning. And saying that utterance is easy when we wake up fresh. It will be totally different if we have so many problematic thoughts the night before. Can we wake up fresh the next morning? I don't think so. And of course we have no time to think that we should say: "Thank God I'm still alive!"
Anyway, at least we are aware that we are still alive. That is a good start to practice our gratitude. In any circumstances, good or bad, happy or sad, we can still express our gratitude for life to still be alive.
