These changes do not take place overnight; nor do they occur automatically. We may need to exert “earnest effort” over a period of years. (2 Pet. 1:5) We must do our utmost to change our inner self. Prayer is the important first step. We need to pray as did the psalmist: “Create in me a pure heart, O God, and put within me a new spirit, a steadfast one.” (Ps. 51:10) We must acknowledge the need to change our dominant mental attitude and ask Jehovah for help. Meditation is the second vital step. As we peer into God’s Word each day, we need to take the time to meditate, or to think deeply, on what thoughts and feelings we need to change. (Ps. 119:59; Heb. 4:12; Jas. 1:25) We must identify any tendencies we may have to be attracted to human philosophies. We need to admit honestly what our weaknesses are and then work hard to get rid of those weaknesses. w19.06 8 ¶1; 10 ¶10; 12 ¶11-12

When making decisions, you must choose a time to implement your decision and stick to it. Avoid waiting for the perfect time to act; the perfect time is not likely to come. (Eccl. 11:4) Be careful not to allow less important things to consume your time and rob you of the energy you need for the more important things. (Phil. 1:10) If possible, set aside time during which you have few interruptions. Let others know that you need time to concentrate. Consider turning off your phone and checking your e-mail or social media at a later time. The result, or outcome, of your decision is like the destination of a journey. If you really want to reach that destination, you will keep going even if a road is closed and you thus must change your route. In the same way, if we focus on the outcome of our decisions, we will not give up easily when we encounter setbacks or detours.​—Gal. 6:9. w19.11 30 ¶17-18

What should be the basis for your decision to get baptized? As a result of your careful study of the Bible, you have learned much about Jehovah​—his personality and his ways. What you have learned about him has warmed your heart and moved you to love him very much. Your love for Jehovah must be the primary basis for your decision to get baptized. Your decision to get baptized is also based on the Bible truths you have accepted. Consider what Jesus said when he gave the commission to make disciples. (Matt. 28:19, 20) According to Jesus, those who get baptized must do so “in the name of the Father and of the Son and of the holy spirit.” What did this mean? You must believe with all your heart the Bible truths about Jehovah; his Son, Jesus; and the holy spirit. These truths are very powerful and can deeply touch your heart. w20.03 9 ¶8-9
