Task Switching
When starting a task, allow yourself at least 15 minutes to feel lousy about it.

Self Hatred
Hating yourself will never bring you closer to yourself. Hate repels all, good included, right at the doorstep.

Your Life Is Your Responsibility
Are you afraid of other people's reactions to your choices? If you let them affect your decisions, you're shifting responsibility. Do not do this. It's not fair to you and definitely not to them. How would it feel if someone did that to you and you'd learn of it?

Shoulder the responsibility of your life. Do not put the burden on anyone else.

Lies of Depression
Remember: Sometimes things aren't how you feel like they are. If you are depressed, that's most of the time. If you accomplished something and failed to feel good about it, that doesn't nullify the value of what you have done. Understand that there is a world beyond your feelings.
Denigrating yourself and everything may feel right, but it doesn't make it correct. Face your feelings first, make them conscious and you'll see them for what they are.

Challenges
Commit past challenges into your memory, so that you can tell yourself, "I've been here before, I can overcome it again."

Be With Yourself
Be with yourself. Regardless of what you have to offer yourself, be with yourself. Whether the arising thoughts and emotions are engaging or not, whether they're good or not doesn't matter. Be with yourself, because it's you.

I Won't Shut Up About The Importance Of Words
Write about emotional states you'd like to be in.
As it turns out, people who are more depressed have a wider vocabulary for all things negative, and people whose default state is more upbeat have wider vocabulary for all things upbeat. Writing is the crowbar to break and enter different moods with.

Remembering playfulness
Too often "to be serious" is synonymous with maturity, and we don't even know to question why we are no longer happy.
Whenever something feels serious, it may have come too near to you. Be wary if it begins to seem like you take everything seriously, and ask yourself why that is.

This, too shall pass
At times of distress, it helps to wake up and realize everything comes and goes at its own pace. We can disturb the natural flow by making a huge deal of it and turning it into a mental puzzle our mind then ruminates on. It's normal for the mind to do this, but it doesn't mean you have to join in and ruminate with it.

Have you checked your narrative?
The words we use in our internal narrative either strengthen our pre-existing beliefs, or weaken them. We shouldn't under-estimate the power our habitual use of words hold.
