new sourdough baker

hi friend rewind :)

i visited home recently. my sister and i went to tj maxx together, and she got me a sourdough starter kit. it comes with a thermometer, cloth cover, silicone base, 34 oz jar, silicone spatula, and a feeding day/level band. i am very grateful for her rather random gift, haha! i am excited. on the back of the box, it gives me some simple instructions for the 7 day process. 

anybody out there got any tips for my very first sourdough starter? any hidden secrets to make it absolutely scrumptious? thank you very much!
