It's all a matter of perspective, isn't it?
What is trivial to someone else may be so important to me. It might be a feeling or an incident, a discovery or a memory or just something that made me smile.
It's so important to realize and acknowledge what's important to ourselves, and to recognize that because we feel it is important, it is important. It's so easy to dismiss such things when others minimize them or trivialize them, and to humbly accept their opinion as correct. When that happens, it's like pinching the tiny tender leaves off a plant.
What appears to be very little, actually, might be really big. Celebrate the tiny things. They enrich your soul.
