The first easy way is by meditating. There is a common misconception that mediating is hard and people will often try to mediate and quit after they realise that in their first session they can't clear their minds. An important thing you need to know is this is normal, in an age where distractions are everywhere it is completely normal for you to struggle to meditate in the beginning. However, if you can continue this practice you will see your appreciation for the simple things in life sky rocket and you can reduce your anxiety or stress by focusing on your breath for a few minutes a day.
