There was a Christian therapist who came in contact with a woman who told her that she was planning on committing suicide; the therapist remained calm and when asked later about it, she stated plainly that her client would not, and that she wasn't concerned. When asked why, the therapist replied, "because she brushed her hair, and put on her makeup this morning." There is a significant amount of truth to this, because the number one sign to see if someone is suicidal is to think that life isn't worth living, so then why would she want to keep up appearances? So then we can ask ourselves, "Are we keeping up appearances with God?" How distanced are we from the problems of life in our worship with God? This is the root of worry. If you can step back and out of creation with your mind, and focus only on what the Scripture says about who God is, then worship becomes overwhelmingly peaceful and a constant state of rest with prayer. If prayer isn't easy for you, make it easy. You need more to go on. You can READ! So go out and find that spot in the Bible that you like or find a new one to meditate on.
So to answer the question directly: Discipline increases self-worth, and self-worth increases discipline, so if you can increase one you affect both assuming you're following Christ. And joy is a result and a motivator for discipline, while joy is the effect or result of having discipline and self-worth. So I told you where to receive joy, now I'll tell you where to receive discipline and self-worth. These are scriptures on discipline:
Hebrews 12:11 "No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it."
Proverbs 13:4 "The soul of the sluggard craves and gets nothing, while the soul of the diligent is richly supplied."
2 Timothy 1:7 "For God has not given us a spirit of timidity, but of power and love and discipline." So we are expected to have discipline, because God gives it to us. Another evidence that God is the giver of our spiritual temperance is Galatians 5:22-23 "But the Holy Spirit produces this kind of fruit in our lives: love, joy, peace, patience, kindness, goodness, faithfulness meekness, and temperance: against such there is no law."
Discipline first, Joy second. Remember the holy order.
