@Ashish_ I always find it helpful to express myself when there is conflict in my mind, and some turmoil in my life. Or when I'm just feeling down. Writing it down helps a lot, yes, but I find myself often having an internal conversation about whatever is going on. It helps to freshen my mind and perspective. I talk to myself within, or I actually talk to God, and it makes me feel so light; like a weight being lifted from my chest.
Sometimes we are moving so fast in our lives with everything going around us so quickly that it becomes overwhelming, almost suffocating. So it's quite important to pause and reflect on how we feel, to regain our balance, reinforce our purpose and to feel calmer.
