Do you ever feel like you just have too many writing materials, such as pens, markers, pencils, etc., and think maybe you should decrease the amount you own? As for myself, I say never! To me planning is like making art.
Think about it...your planner is your blank canvas. What are you planning to paint? Will you use bright or dark colors to capture your feelings? What do you want the end result to look like? Once the artist has an idea of what to create and their materials are set up a certain way then they begin creating their masterpiece.
Same thing applies for planner lovers! Your planner is like your canvas. Are you going to plan with colorful markers...maybe base the color scheme on the current season? Maybe you like to use vibrant colors like pastels or neon, or maybe just neutral colors to give it a subtle look. What about gel pens? Maybe you want to doodle design in zen style with those fabulous gel pens. Or maybe you just want to use pencil and create a simple bullet point list to help you get your day organized, but also give it that nice, clean, sleek look.
Whatever you choose to use, have fun creating your planner pages. Every day and week is a new opportunity to make a new masterpiece. Become your own artist and create your own masterpiece in your planner. Your planner will be in style more than any other generic calendar.
