Like Andrew, it's very easy for me to be negative. Like so damn easy - depression and anxiety and low self esteem and just the ease with which I can tear myself apart mean any positivity and hopefulness you see from me has been the result of a conscious effort. Thankfully I want to care about people and be empathetic so I have motivation to move past my negativity, but it's still often hardest to be understanding, forgiving, and supportive of myself.
The point is that what I've been trying to do for myself, and have been trying to be more active at doing for others, is to remind us that the point of life is to live it, and to inspire us to find what brings us joy. Some joys are silly, some are deep, some are ones we keep for ourselves, and others we share with whomever we can. But joy is valid, no matter how pointless or stupid it may seem, because the point of our joys is to give us the strength to deal with the pains and struggles of life. Because this isn't about hiding away from the world, it's about living in it, and helping others to be able to do the same.
