But the Holy Spirit produces this kind of fruit in our lives: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.”

This is actually less of a meditation and more of a spiritual practice (that will lead to and include meditation). Find at least 15 quiet minutes and sit with this list of Spirit-fruits. Since these are fruits the Spirit produces in us (not self-made fruit), ask the Lord to highlight one of these that needs cultivating at this moment. It might be one you are really lacking in, but it also might be one you particularly excel at already. The Lord may want to shore up a weakness or further develop a strength. Try not to assume you know or go in with preconceived notions. Let the Spirit tell you.
When you hear from the Lord and have zeroed in on one, then meditate on what that fruit means, what it would like for the Spirit to produce that fruit (or more of that fruit) in your life. The Spirit will give you specific direction on tangible things you can do to participate in the production of this fruit. After all, even though the Spirit produces the fruit in us, we are not uninvolved in the process. Note that one of the Spirit-fruits is self-control; that is not a mistake or a logical contradiction. The Spirit produces the fruit, but our will has to be compliant with the Spirit’s work for fruit to be produced.
The Spirit will give you one specific fruit to work on for this moment and specific ways to work on that fruit – if you take time to listen.
