Hey everybody, whenever we're sharing any learning resources, job openings, or anything in our community, try to show your support by reacting to messages so that I'll get an understanding people are applying for various opportunities and are using resources.    Also, try to show your support on LinkedIn posts too, because whatever I'm sharing is only visible to people who know about me, and others don't get resources. But if you show your support, you're not only helping yourself but others too. Because of your support, things will reach out to many people, and you're also making your active presence on LinkedIn. Sometimes job hiring might get closed if you don't apply on time, but if you're supporting, then you can get more opportunities for sure.  So from going forward try to show your support by reacting to each things that are shared in the community by either 👍, 👏, 🔥, ❤

Hey hustlers, I hope you're doing well and welcome to 𝗛𝘂𝘀𝘁𝗹𝗲𝗿𝘀 𝘁𝗼 𝗯𝗲𝗰𝗼𝗺𝗲 𝗮𝘀𝗽𝗶𝗿𝗶𝗻𝗴 𝗗𝗮𝘁𝗮 𝗔𝗻𝗮𝗹𝘆𝘀𝘁 𝘁𝗼 𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝗮𝘀 𝗗𝗮𝘁𝗮 𝗔𝗻𝗮𝗹𝘆𝘀𝘁 challenge. So today is day 0 and I'm going to share what this challenge is all about and what things is going to cover. So for this challenge, we are going to cover all skills and tools required for a data analyst role from scratch to the advanced level, with a focus on a focus on hands-on practice and some small-scale projects also going to be covered.   In this challenge, as I already told you all, we are going to work not only on the learning part but also on making us mentally, emotionally, and physically stronger over time.   Today is just the introduction of this challenge. Nothing much for the learning side, but for this challenge, I'll try my best to give you as many free learning resources as possible so you don't have to spend more money on anything.   But for this challenge, there are a few things that are needed, which are either a laptop or a desktop with Internet connectivity. These two are the most important, and if you have only a phone with internet connectivity, then that's that's also okay, because I can understand that not all of us can have these resources.   The other part of challenge is how we are going to work on ourselves to make us mentally, emotionally, and physically stronger. So for this there are things we have to do every single day, and I know this will not be as easy as it seems right now, but over time you'll be able to do it without any excuses because we're hustlers who don't give excuses, right??   Things apart from learning we have to do are: 1. Taking enough amount sleep of 6–8 hours daily 2. Eating only healthy and home-made food and trying to avoid junk food as much as possible to eliminate sugary and packaged food 3. Daily 30 minutes of exercise. Here, you don't need to join any gym; you can do just walking and some yoga to make us stronger.  4. Drinking 3–4 litres of water 5. At least 2 minutes of deep breathing will make us calm and focus on only positive things. This will eliminate all your anxiety and negativity. 6. Try to give a minimum 1 hour for learning new skills, which can be helpful for getting a better job or making money.   You can add extra things as per your needs. I hope you're with me for this challenge, right? Show your support and enthusiasm for reacting to this message.
